Iontra develops an integrated RISC-V charge-control and fuel-gauge microcontroller that applies electrodynamic principles to optimize battery charging. The company is a fabless supplier of low-cost, small-footprint battery charger MCUs with embedded cybersecurity and advanced high-speed peripherals for OEMs. Iontra says its charge technology is chemistry-agnostic and can increase battery cycle life and charge speed up to and greater than 200%, support cold charging to -20°C, and reduce plating and dendrite formation. Its technology has been validated by approximately eight million cycling hours in-house and tested by independent labs including the National Renewable Energy Laboratory, Novonix, and the University of Michigan. Iontra plans to make MCU samples available mid-2025 and expects release to production in 2026, and the company is preparing to support customers launching Iontra-enabled products in the near term. Financially, Iontra completed a $45M Series C and has raised $120.3M to date, and it recently received a $2.15M ARPA-E circular grant. Iontra is an innovator of next-generation battery charging technology that aims to improve charge speed, cycle life, capacity utilization, cold-weather charging, and safety for lithium batteries. The company says its breakthrough solution delivers the performance that next-generation batteries are promising to deliver years from now. Iontra announced an additional $29 million Series B financing, bringing its Series B total to $67 million and total capital raised to date to $80 million. The additional Series B was led by Volta Energy Technologies and Riverstone, with support from Flag Asset Management and other investors.
